There are four colligative properties: boiling point elevation, melting point depression, vapor pressure lowering, and osmotic pressure. These properties can be observed by comparing the original properties of the solvent with that of the ...
A method to determine the drought resistance of plants includes imitating the given level of the drought by means of dehydrating the cytoplasm, while keeping the plants in a non-electrolite solution with the corresponding increased osmotic pressure, measuring the specific parameter of a solution with...
What should be done before measuring an unknown pH of a solution using a pH meter? What is acidity? What is pH? How to calculate the volume of air in a breath? What is water pollution? Distinguish between point sources and non-point sources of water pollution and give an example of eac...
The unsteady-state permeate flux response to a step change in transmembrane pressure is shown to result in unique flux–pressure profiles for the three types of solutes common in membrane ultrafiltration (UF): (a) solutes which exert an osmotic pressure but do not form a ‘gel’; (b) solute...
If the concentration of the specific ions is changing during charging, the average water density is also changing. Another reason for water densification might be an increased osmotic pressure if ion concentrations increase during charging. However, ion concentrations do not exceed 1 M and the ...
To a good approximation it is simply a bag of fluid, a concentrated solution of hemoglobin surrounded by a thin macroscopically homogeneous membrane. Thus, the diverse resting shapes that it exhibits can be thought of as (locally) stable mechanical equilibrium shapes of the membrane. This membrane...
A method and apparatus for measuring the presence or absence of reaction between a first and second material of interest by measuring osmotic pressure changes of reaction detector. The reaction detector is capable of measuring the small changes in pressure that occur due to osmotic pressure shifts ...
In an osmometric measurement device and a method for determining the content of an analyte in a solution of a mixture of substances including the analyte, the mixture solution is admitted to a conduit of an osmotic cell structure having inner and outer cells filled with an osmoticum and ...
Inversely, when the experimental evolution of the permeate flux is introduced in the calculation, it is possible to determine osmotic pressure or diffusion coefficients as a function of solute concentration with a good precision. The results obtained for four different kinds of well-defined non ...
